Any CQI parameter, apart from format channel 2 cqiadjstep and puschpara?

We are getting rollout capacity sites and CQI average is around 7 in most sites and I am able to improve till 7.5 may be 7.7.
I want to get more than 8.
Not all sites but most are getting stuck there.
And traffic dip should not be there in that rollout.
Which is also a challenge without disturbing NBR sites.

Can any share ericssion cqi parameter
